What if longan doesn't bear fruit?

In the process of planting longan, we will find that many longan trees will have no fruit or very little fruit, so why? When longan trees do not bear fruit or bear little fruit. This is a great loss for growers. When longan trees fail to bear fruit, what should we do? What problems should we pay attention to in the process of planting? Let's read the following interpretation.

1. Why didn't longan bear fruit?

Why can longan not bear fruit? There are many reasons for this phenomenon, so we need to analyze it from different aspects. For example, the differences in longan varieties, some varieties are not suitable for local planting, then it is very likely to be unfruitful. The second is that the management is not in place, such as no reasonable pruning of branches and leaves, no scientific management of water and fertilizer, ploughing, weeding and soil cultivation, and so on. There is no good prevention and control of diseases and insect pests, resulting in the harm of diseases and insect pests to longan trees, resulting in the phenomenon of no fruit in longan trees. Finally, the influence of climatic conditions on longan trees is relatively great, because the climatic conditions in China change greatly, and the climate may change abruptly in a certain year, resulting in temperature, rainfall, light and other do not accord with the growth of longan trees, resulting in the phenomenon of no fruit.

2. Solution

Longan tree appears the phenomenon of no fruit, growers in order to reduce the loss of planting, then need to solve this problem. In general, the first thing we need to do is to understand the growth characteristics of longan tree, and then choose the planting site according to its growth characteristics. The second is to choose the right variety according to the local environment. There is no partial application of nitrogen fertilizer, scientific fertilization, according to the different growth periods of longan trees, the scientific use of organic fertilizer, micro-fertilizer and inorganic fertilizer. The moisture in the field should be managed reasonably to maintain a certain humidity in the field, but there can be no stagnant water.

3. Points for attention

There are also many things we need to pay attention to when planting longan. First of all, we should prune the longan tree to ensure the ventilation and light transmittance of the crown, and sort out some dense branches, weak branches, sterile branches, fruiting few branches, long branches and so on. The second is to increase the proportion of female flowers, so as to improve the fruit yield of longan. There is to postpone flowering, improve the pollination rate of female flowers, so as to improve the fruit setting rate of longan. Then in the full bloom or fruit setting period of longan, we should thinning flowers and fruits reasonably to ensure the yield and quality of longan. Finally, it is aimed at longan tree diseases and insect pests, scientific control, such as anthrax, soot, leaf moth, bugs and so on.

When longan is planted, there are many reasons why it will not bear fruit, but in fact, the main reason is the problem of planting technology. If there is professional planting technology and rich understanding of longan planting, then these problems will be much less in the process of planting.
